In the present work we have focus our care on the controversial intermediate salt : Ni(NO 3) 2. 5.5H 2O To prepare this phase, we have carried out, in the range 60-80°C, a controlled evaporation of a solution of nickel nitrate, hexahydrate resulting from the melting of a 100g Ni(NO 3) 2. 6H 2O batch sample in an isothermal pilot reactor. The proof of its existence is given, for the first time, by powder x-ray diffraction data.
